[gentoo-user] Two new-install questions
1) Look Ma... no cpio. During my first attempt to build a kernel, it died because the process couldn't find "cpio". I ran "emerge -1 cpio" and tried again, finishing successfully. "emerge -p --depclean" wants to remove it, which should not be happening. To overcome that I ran "emerge --noreplace cpio" which put cpio into my world set, keeping it safe. Why is this happening in the first place? 2) When building xorg-server I got a news item about the "suid" flag soon no longer being default for xorg-server. I forced it manually on my laptop and desktop. The other 3 options were... * systemd... no thanks. * elogind... with PAM doing the authentication... no thanks. I've tangled with PAM in the past once too often. * some memory-heavy "desktop environment" on my 3-gigs-ram-laptop... no thanks. -- Walter Dnes I don't run "desktop environments"; I run useful applications

Gimp can in fact do this, I just tested it. You'll need to mess with transparency perhaps, but as a proof-of-concept you can "paste as new layer" with a PDF page layer from another file.

It depends whether the `gpm` USE-flag is set or not. From the ncurses ebuild:
(See [1] for documentation regarding the ${MULTILIB_USEDEP} eclass variable.)
DEPEND="gpm? ( sys-libs/gpm[${MULTILIB_USEDEP}] )" [2]
The list of architectures you're seeing is an expansion of ${MULTILIB_USEDEP}
as defined by the `multilib-build` (or in this case, `multilib-minimal` eclass);
this can be removed from the output by passing the local option -U to depgraph.
As all of these are disabled, I'm guessing you're not running a multi-lib
profile.
You're saying that the architectures are all disabled because there's a
(-) following all the flags? In that case, it would seem that no
architecture was enabled...
My profile is default/linux/x86/17.0, wouldn't it have a no-multilib
in it if it were so?
Have I done something to disable all architectures?
Note that there's a gpm USE flag for ncurses, but it's *--*
What do you mean, "but it's *--*" ? Do you mean it's disabled ?

I see in the ebuild (the line before your link):
IUSE="ada +cxx debug doc *gpm* minimal profile static-libs test
threads tinfo trace unicode"
The definition of IUSE I find is in ebuild(5):
IUSE This should be a list of any and all USE flags that are
leveraged within
your build script. The only USE flags that should
not be listed here are
arch related flags (see KEYWORDS). Beginning with
EAPI 1, it is possible to
prefix flags with + or - in order to create default
settings that respec-
tively enable or disable the corresponding USE flags.
It seems to me from that that IUSE just catalogs the possible USE flags,
and a USE Flag is only a default if prefixed by -/+.

You already have many suggestions, but I'll mention app-text/pdfjam (and pdfjoin it provides) just for completeness. I use it like this to merge scanned documents: $ pdfjoin --rotateoversize false --outfile x.pdf y-*.pdf It's command line and only depends on virtual/latex-base so may be a nice option if you already have a latex installed.

I'm sure there are some GUI-based options that you might prefer, but pdftk is great for command line use. I'll go ahead and offer this script that takes as input a bunch of pdf files, and it combines them all adding blank pages as needed to make them all even. This is used to generate a combined PDF suitable for double-sided printing on a single-sided printer if I have a bunch of PDFs I want to print in batch. #!/bin/bash for file in *.pdf do #get the number of pages numberofpages=`pdftk "$file" dump_data | sed -e '/NumberOfPages/!d;s/NumberOfPages: //'` echo -n "$file" 'has' $numberofpages 'pages, ' uneven=$(($numberofpages % 2)) if [ $uneven == 1 ] then echo 'which is uneven - added 1 more' tempfile=`mktemp` pdftk A="$file" B=/usr/local/share/blank.pdf cat A B1 output "$tempfile" mv $tempfile $file else echo 'which is even' fi done pdftk *.pdf cat output out.pdf -- Rich
